why cant people just understand

I was on the phone with my mother today and she was asking about the baby things I have and what I am doing with it all. I told her I still havent moved it and its still set up. I am just not ready to pack it all. She told me that she was retuning the crib she bought for him. I told her that was fine but I am not returning what I have. She then asks me if that is healthy? and that I need to say goodbye to him and forget about it. I told her he was my son and I will NEVER forget him. She then says that people are concerened becuase Im not letting go and want to have a memorial for him on his due date. She then ask if Im ready to have another baby. I told her yes I want to try again and this baby will know who Max is. Just because he is not here doesnt make him any less my son.I never had a funeral for him because I was just in shock with every thing at the time so decided to have a memorial on his due date. She then tells me that I just need to have one by myself and stop trying to involve everyone with my problems and need to move on. I told her I didnt care if anyone came. He is my son and I am goin to do this for him whether they like it or not. She then again tells me that this is not healthy, he is dead and get over it. I blew up at her and then hung up on her.Is it wrong or unhealthy that I want to have a memorial for my son? Just because he wasnt "alive" outside of me doesnt make him any less my son and I am really hating everything in this world again and just want to be with my son. F&*K everyone that doesnt understand in my family.I am just trying to make it thru this and they are just making it worse.
